Re: Ettercap SEND L3 ERROR

How would setting the MTU to 3000 which is double the ethernet norm fix the problem??

Pffbt..[quote]I made a discovery today. I found a computer. Wait a second, this is cool. It does what I want it to. If it makes a mistake, it's because I screwed it up. Not because it doesn't like me... Or feels threatened by me.. Or thinks I'm a smart ass.. [/quote]

It's pretty obvious. 42 is the answer

All right, no joke this time, I'm wondering the same. MTU is Maximum Transmit Unit. And i believe this is the length of the packet frame, but as said snafu777, 1500 is the standard. Doubling it doesn't make much sens (afaik).

SEND L3 ERROR: 2654 byte packet

Well, I guess you say that because of supra but... Dunno, doesn't seem right to me.

AW: Ettercap SEND L3 ERROR

Seems like doesn't work..., remember the Error is about a denied Permission on forwarding packets an Layer3. I've never seen a higher MTU on MY Network as 1500 in all these years, also this error was not common in the previous versions of Backtrack.

Layer3/L3:

This is also referred to as the OSI (Open Systems Interconnection) Network Layer. It provides the paths for the transfer of data between systems and across networks. The paths between systems may include switched services, and interconnections of multiple subnetworks on route. An example of a protocol operating at the network layer would be IP (Internet Protocol).

The MTU (Maximum transmission Unit) is the greatest amount of data that can be transferred in one physical frame on the network

Your idea with the MTU is not right, but you're thinking into the right way =), on my researches i found 2 interesting points.

First is the MSS (Maximum Segment Size) defines the largest segment of TCP (Transfer Control Protocol) data that the Winsock is prepared to receive. When a connection is established, the two ends agree to use the smaller of each end's value.

The Second Point is the Header refers to the first part of a data cell or packet, containing such information as source and destination addresses, and instructions on how the telecommunications network is to handle the data. The header is part of the overhead in a data transmission protocol.

Sorry this should not be an lesson, also i don't wanna come you to near... Just wanna give my opinion to the error. I've spend so much hours on fixxing this error... Seems like there must be an conflict with the routing... Remember the ipv4_forwarding file? (proc/sys/net...). Seems like there a more conf-files which we must set...

I'm not an expert or anything like that... i repeat that i only wanna try and learn =)
